The investigators hypothesize that 3-months of nutritional support using this FVB will result in additional reductions in marginal gingival inflammation (bleeding) and additional reductions in probing pocket depth (mean & cumulative), over and above any placebo-related or behavioral effect. In addition, the investigators hypothesize that 3-months of nutritional support prior to a standard non-surgical therapy in conjunction with a continuation of the nutritional support for 3 months will result in further additional reductions in marginal gingival inflammation and probing pocket depth, over and above any placebo-related or behavioral effect following standard non-surgical therapy.
